Many people experience being unable to smell their perfume after a short period of time. This phenomenon is called olfactory fatigue or adaptation, or selective anosmia. It occurs when your brain gets used to the fragrance, causing it to tune it out. Other factors that can affect how your fragrance smells include your body's pH balance, the weather, application techniques, and incorrect perfume storage. To combat olfactory fatigue, it is recommended to use other fragrances now and then, so your brain is less likely to adapt. Additionally, storing perfume in dark, dry places and applying it to clean, moisturized skin can help prolong the scent.

What You'll Learn
Olfactory fatigue or adaptation
If you can't smell your perfume anymore, it could be due to a phenomenon known as olfactory fatigue or adaptation. This occurs when you are exposed to a particular scent for an extended period, causing you to become desensitized to it. It is a normal and temporary response, and your sensitivity to the scent will return after leaving the area or taking a break from exposure.
Olfactory fatigue is an example of neural adaptation, where the body adjusts to stimuli to prevent overloading the nervous system. In the case of scent, odorants, or small molecules present in the environment, bind to receptors on olfactory receptor neurons (ORNs) in the nasal cavity. This triggers a response in the brain, allowing us to perceive different smells. However, with prolonged exposure to the same odorant, the olfactory neurons' sensitivity decreases over time to prevent overstimulation. This leads to olfactory fatigue, where you may no longer be able to smell a particular scent, even though it is still present.
The scientific explanation for this phenomenon involves the role of Ca2+ ions. When odorants bind to receptors on ORNs, Ca2+ ions flood into the cell, causing depolarization and signaling to the brain. However, the increased presence of Ca2+ ions also activates a negative feedback loop, which stabilizes and lowers the olfactory neuron's sensitivity over time. This process is known as olfactory adaptation, where the olfactory receptors become desensitized to prolonged odorant exposure.
To counteract olfactory fatigue, it is recommended to use different fragrances intermittently. This prevents your brain from adapting to a particular scent, allowing you to enjoy your favorite perfume more when you wear it. Additionally, taking breaks from exposure and leaving the scented area for a while can help restore your sensitivity to the fragrance.
It is important to distinguish olfactory fatigue from anosmia, which is the permanent loss of the sense of smell. Olfactory fatigue is a temporary condition where you become unable to distinguish a specific odor after prolonged exposure. Anosmia, on the other hand, can be caused by infections, injuries, or other factors, and it results in a reduced or lost sense of smell overall.

Dry skin
There are several reasons why you might not be able to smell your perfume anymore. One reason could be that you have dry skin. If you have dry skin, the scent molecules of the perfume may find it harder to 'sink' into your skin. This can be addressed by using a simple body cream or oil, or even a fragrant body cream that can layer well with your perfume.
Another reason for not being able to smell your perfume could be 'olfactory fatigue or adaptation', also known as 'nose fatigue'. This occurs when your brain gets used to a particular fragrance, causing you to gradually stop noticing it. To address this issue, you can try alternating between different perfumes or fragrances. Taking a walk to get some fresh air or stepping away from the area where you sprayed the perfume can also help reset your sense of smell. Additionally, coffee beans can be used to inhale and clear your nose, enhancing your ability to smell.
The composition of the perfume itself might also be a factor. Light fragrances composed of volatile notes, such as citrus, tend to dissipate quickly and may not last as long as other perfumes. In such cases, reapplying the perfume or opting for a scent with longer-lasting notes might be necessary.
It is important to note that not being able to smell your perfume after a while is perfectly normal, and there are several ways to enhance your fragrance experience, such as rotating through different scents or combining them with fragrant body creams.

Incorrect perfume storage
One of the most common mistakes people make when storing perfume is keeping it in the bathroom. The humidity from the shower or bath can cause the perfume to oxidize, altering the scent and causing it to smell off or change colour. Temperature fluctuations in the bathroom can also be detrimental to perfumes, disrupting the molecular integrity of the perfume and causing it to weaken over time.
Leaving perfume bottles on a windowsill or a shelf exposed to direct sunlight can also cause the perfume to spoil. Temperature changes and exposure to sunlight can cause the perfume to undergo chemical reactions, altering its fragrance and composition.
Another common mistake is forgetting to close the bottle after use, leaving the perfume exposed to oxygen, which can cause spoilage and evaporation. It is important to always keep the lid on perfume bottles to prevent oxygen from entering and altering the scent.
While it is not necessary to store perfumes in the refrigerator, keeping them in a cool, dry, and dark place, such as a closet or cabinet, is ideal. This helps maintain a constant temperature and protects the perfume from light and moisture, preserving its original scent and quality.

Weather conditions
Humidity can also affect how a perfume's scent is perceived. Higher humidity levels can cause lighter notes to bloom, giving the fragrance a different character, while dry conditions might emphasise the base notes. The chemical composition of the scent also plays a role in how humidity affects the fragrance.
To make perfumes last longer in cold weather, it is recommended to layer the perfume on top of a fragrance-free moisturiser. This provides a foundation for the scent to cling to and amplifies its longevity. It is also suggested to scent clothes and accessories, such as scarves and gloves, in addition to the skin.
In warmer weather, it is recommended to carry a travel-sized version of the perfume for easy touch-ups throughout the day. Applying perfume to pulse points and moisturised skin can also help the fragrance develop and last longer.

Selective anosmia
Anosmia is a well-known symptom of COVID-19, and it can sometimes persist for years after recovery. It is a condition where the patient loses their sense of smell. Selective anosmia, on the other hand, is the inability to perceive specific odours.
A study on the occurrence and composition of selective anosmia to several monomolecular aromatic compounds in a group of young individuals, including those with a history of COVID-19, found that the prevalence of selective hyposmia and anosmia in the population is far higher than anticipated. The study observed prevalent selective anosmia to some substances: methylcam phenylcyclohexanone, methyl dihydrojasmonate, patchouli ethanone, galaxolid, and maltol. The same individuals were able to classify other substances as intense, demonstrating the selective nature of anosmia.
Another study found that olfactory detection thresholds were significantly lower for male subjects than female subjects for the aromatic aldehyde bourgeonal, which is involved in sperm chemotaxis. No gender difference was found for helional and n-pentyl acetate.

Frequently asked questions
This phenomenon is called olfactory fatigue or adaptation, meaning that your brain simply gets used to the fragrance. Your brain associates it with your personal body odour and tunes it out.
You can try using other fragrances now and then so that your brain is less likely to adapt. Alternatively, you can take a break from your scent for a few days before going back to it.
Yes, the weather can affect how long a fragrance lasts and how it smells. Dry skin can also make it harder for scent molecules to sink into your skin.
